+### Publishing to IPNS with IPFS Desktop
 With IPFS, when you publish a new piece of content, it has a new CID, meaning the data is immutable. This is great when you want to identify a certain piece of data, and make sure you know what you are accessing. There is, however, a use case for mutable data, such as a website.
 
 You want to give people one address where they can access, say, a website, but want to be able to make updates to it, such as adding an event page, or updating a typo. This is where IPNS comes in.

-#### Using Pinning Services with IPFS Desktop
+### Using Pinning Services with IPFS Desktop
 When you add files and folders to IPFS, typically they are only available for retrieval from others when your own node is up and running, unless someone else just happens to pin your file on their node from the network.
 
 Pinning services provide the service of pinning and maintaining the availability of files on IPFS for you, even when your own node isn't running.
